Explanation

Six people A, B, C, D, E, F sit around a circular table facing center.

1. C is opposite A.  

2. E is opposite B.  

3. D is second to the left of C.  

4. A is second to the right of B.  

From 1: Place A and C opposite each other.  

From 2: Place B and E opposite each other.  

From 3: D is 2nd left of C.  

From 4: A is 2nd right of B.  

Arranging all conditions, the order clockwise is:  

B, A, D, C, E, F  

Check:  

A is 2nd right of B ✓  

C opposite A ✓  

D 2nd left of C ✓  

E opposite B ✓  

Now check neighbors of F: B and A.  

So F is sitting between B and A.

The pattern is:

30 → 18 (−12)

18 → 15 (−3)

15 → 7 (−8)

7 → 4 (−3)

The subtraction alternates with a larger number and −3:

−12, −3, −8, −3

So, the next number is:

7 − 3 = 4

Explanation

Let the daughter's present age = x.

Father's present age = 3x

After 12 years:

Father's age = 3x + 12

Daughter's age = x + 12

According to the question:

3x + 12 = 2(x + 12)

3x + 12 = 2x + 24

x = 12

So, the daughter's present age is 12 years.

The pattern is:

3 × 2 + 2 = 8

8 × 3 + 3 = 27

27 × 4 + 4 = 112

112 × 5 + 5 = 565

565 × 6 + 6 = 3396
